In the introduction of the paper, we state that LaTeX embodies the principle of “What you get is what
you mean” (WYGIWYM), which implies that the document is not directly displayed on the screen and
changes, such as format settings, are not immediately visible. Although this is true, LateX users often
use synchronous-formatting interfaces that display the printed page in standard PDF which, in
principle, is more WYSIWYG than Word.
The study was conducted when most of the participants in the Word groups used Word Version 12.
